Specification of Letters Patent.

Application filed March 9, 1912. Serial No. 682,714.

To all whom it may concern Be it known that I, VVILL'IAM L. DALY, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented new and useful Improvements in Mixing Devices, of which the following is a specification.

This invention relates to mixing devices,

and it has for its object to produce a simple, v

inexpensive and eilicient device whereby materials in powder form may be mixed together.

A further object of the invention is to produce a device of the class described comprising a mixing drum and a receptacle into which the material may be discharged from the mixing drum, said receptacle being provided with an inclined bottom and with a discharge valve at the lower end of said bottom to enable the contents to be discharged as required for use.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawings,-l igure 1 is a front view of a device constructed in accordance with the invention. Fig. 2 is a vertical sectional view taken on the line 2--2 in Fig. 1. Fig. 3 is a horizontal sectional View taken on the line 3-3 in Fig. 1. Fig. 4 is a horizontal sectional view taken on the line 44: in Fig. 1. Fig. 5 is a detail top view of the drum.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved device, which is particularly adapted for the use of confectioners and ice cream manufacturers for the purpose of mixing ingredients in the manufacture of ice cream powder, is mainly constructed of sheet metal which is galvanized or otherwise protected from corrosion. The

casing A, the bottom members of which 1, 1 and 2 converge downwardly and upwardly in the direction of a discharge aperture 3 in the front wall l of said casing, is supported on legs 5, and said casing is provided with a lid or cover 6, said cover being hingedly connected with the upper edge of the rear Wall 7 of the casing. The side walls of the casing afford bearings for a shaft 8 carrying a drum B which preferably includes a central cylindrical portion 9 and tapering or frusto-conical end portions 10. The shaft 8 which extends axially through the drum is provided exteriorly of the casing with a crank 11 whereby it may be rotated. The cylindrical central portion of the drum has an opening for which a hingedly supported closure 12 is provided. A catch 13 is also provided whereby the closure 12 may be retained in a closed or obstructing position with reference to the opening 14. Within the drum is mounted a paddle 15 constituting a beater or breaker whereby the thorough mixing of material introduced into the drum is promoted and facilitated when said drum is rotated.

The front wall 4: of the casing 8 is provided adjacent to the discharge aperture 3 with guides 16 supporting a slide or valve 17 which constitutes a closure for the opening 3 and which may be readily manipulated and adjusted to regulate the escape of the contents of the casing through the aperture 8. A discharge chute 18 extends downwardly from the lower end of the bottom of the casing to facilitate the discharge of the contents of the casing into a receptacle placed underneath.

The operation and advantages of the invention will be readily understood from the foregoing description when taken in connection with the drawings. The ingredients that are to be mixed are placed Within the drum through the opening 14, the closure 12 being meanwhile held open, as well as the lid 6 of the outer casing. After placing the ingredients within the drum, the closure 12 and the lid 6 are shut tightly, and the drum is now rotated by means of the crank 11 until the ingredients have been thoroughly mixed. The lid 6 and the closure 12 are now again opened, and the drum is rotated or inverted to permit the contents to escape through the opening. 14 into the receptacle A from which it may be removed as wanted a discharge neck formed upon the circumference 01' said drum, a closure connected to said neck, a paddle mounted transversely in 15 said drum diametrically opposite said discharge neck, and a lid adapted to close said chute.

In testimony whereof I aiiix my signature in presence of two Witnesses.
